Marijuana Legalization: Medical Benefits and Policy Risks

Introduction: The Debate Over Marijuana Legalization

The use of marijuana has been prohibited since 1937, when United States law strictly banned its use. In the years that followed, debate has re-emerged over whether marijuana should be legalized, especially for medical purposes (Pacula & Smart, 2019). Research has shown that hospital discharges related to marijuana use and emergency department visits have increased. Nevertheless, following legalization in several states, criminal arrests and court cases related to marijuana have decreased — a trend discussed further in later sections.

Medical Benefits of Cannabis

Several studies have indicated that marijuana has legitimate medical applications. Research has shown that oral cannabis extract (OCE) effectively treats neurological disorders such as central pain, muscle spasms, and urinary dysfunction (Koppel et al., 2014). Cannabidiol (CBD), one of the key chemical compounds found in the marijuana plant, is extracted and used in a range of medical applications. The therapeutic effects of cannabis are wide-ranging, providing significant relief from chronic pain, chemotherapy-induced nausea, and muscle spasms associated with multiple sclerosis (Edalatpour, Attaluri & Larson, 2020).

Public perception of marijuana was historically negative, largely shaped by concerns about opioid use and addiction. However, this plant-based drug can be used in different forms and quantities to produce positive health outcomes. It may serve as a supplement for managing chronic pain and can be prepared as herbal medicine or medicinal cannabis pills (Bridgeman & Abazia, 2017).

Compounds such as THC and CBD are considered relatively safe, given their positive health outcomes and the low number of deaths directly attributed to their use. Research has also shown that individual metabolism affects how the body responds to marijuana, and that biological characteristics are influenced accordingly. CBD's overall risk profile is lower, and for this reason, decriminalization is increasingly advocated based on its medical benefits. However, when pharmacy and policymaking intersect, the challenge becomes significant for government authorities, as the health and safety of citizens is at stake.

Social and Youth-Related Concerns

Many U.S. states have legalized marijuana, and its use has since extended beyond medical contexts, becoming increasingly common among the general public — particularly youth. Legalization laws have normalized marijuana's use, and the cultivation, provision, and distribution of cannabis have all surged (Pacula et al., 2015). Recreational use has grown substantially and has become potentially harmful as social accessibility has expanded under new legal frameworks. In some jurisdictions where medical marijuana is permitted, clear guidance on how patients may access it — such as through home cultivation or licensed pharmacies — has been absent. State laws that legitimized marijuana often failed to address the social consequences of surplus or recreational use.

Through the lens of social identity theory, the legalization of medical marijuana has become a focal point of regulatory debate. Research indicates that regular marijuana users are far more likely to support legalization for medical purposes than non-users, and that status insecurity is more pronounced among in-group members who use marijuana compared to those outside such groups (Geiger-Oneto & Simkins, 2017).

Despite marijuana's medical benefits, it continues to draw criticism for its use among youth and adolescents in the United States. It is associated with harmful health effects in young adults and has been linked to criminal activity. The increased availability brought about by decriminalization policies has amplified usage rates, as demand for marijuana and its broader applications continues to grow (Ladegard, Thurstone & Rylander, 2020).

Determining appropriate quantities and conditions of use will require revisiting recent policy changes, which present a complex clinical picture. Health policies would need to be updated to minimize potential adverse effects if marijuana is to remain legal. Targeted interventions should be outlined, and adequate education about proper use should be made mandatory.

Conclusion: Balancing Benefits and Risks

From the discussion above, it can be assessed that marijuana should remain legal where it has been legalized, but that legalization must be accompanied by careful policy regulation. The benefits and risks must be weighed carefully, and permissible quantities should be determined on a drug-by-drug basis. Marijuana clearly has positive medical applications, but it also poses genuine risks to youth health as access has become easier. With increased legal access, marijuana-related crime rates have dropped and court cases have decreased.

The responsibility for accurate and effective decriminalization rests heavily with state governments. Applying a substantive theory framework, the various stakeholder groups — those who support and those who oppose legalization — have been examined through the available literature. Those who advocate for legalization point to marijuana's demonstrated positive health impacts. Those who oppose it highlight the dramatic rise in youth usage and the documented negative mental health effects.

Additionally, through the lens of social identity theory, certain groups support legalization in order to align themselves socially with peers who already use marijuana. This dynamic is especially relevant among college students, where drug use in social settings is well documented. In reference to the same theory, it can be inferred that groups who use marijuana seek legalization partly to secure a recognized social identity. Substantive theory, meanwhile, provides a framework for understanding the various social contexts and groupings in which marijuana use is most prevalent. The application of legalization will be most visible within these groups, and future comparisons will help determine whether society has benefited from legalization or not.
